LITTLE ROCK  DEAR READERS: Valentine’s Day is just around the corner, and there is no better way to show your valentine your love than by sending a specially postmarked card. Loveland, Colo., is celebrating the 67th anniversary of its world-renowned valentine remailing program this year.

Each year, Loveland (also known as “The Sweetheart City”) holds a contest to select a winning design and verse that will be featured on the year’s stamp. The city’s 60 volunteers hand stamp more than 160,000 cards from all 50 states and 110 countries.

If you would like this special Valentine’s Day stamp, address and stamp each card (46 cents for standard cards). Place all of the valentines into a large, first-class envelope addressed to Postmaster, Attention: Valentines, 446 E. 29th St., Loveland, Colo. 80538-9998.

For your valentines to make it in time, they must be received in Loveland by Feb. 8 if sending within the United States. (Foreign cards need to be received no later than Tuesday.)

Looking for a different postmark? Try Romance, Ark. (72136), Valentine, Neb. (69201), Loving, N.M. (88256), Darling, Miss. (38623), or Bliss, N.Y. (14024). Just place all cards in a large envelope and address it to Postmaster, Valentine Re-mailing and the city of your choice.

DEAR HELOISE: I came up with an idea regarding window air-conditioner units and pool noodles. We had a gap on either side of our unit, as well as a small gap at the bottom. I came up with the idea of using a pool noodle to fix it. Just measure and cut the length you need for each side, and because they are foam, you can squish them in, and they form a great seal. Works perfectly, and it was a cheap fix.

DEAR HELOISE: I saw that you gave certain commands for PC users on how to cut, paste, copy, etc. You forgot a very important one, which I use all the time:

Ctrl + Z is to undo an action.

It’s very important to someone who may have accidentally deleted something.
